CARAPHRACTUS Walker, 1846 View in CoL

( Figs 246–273 View FIGURE 246 View FIGURES 247–251 View FIGURES 252–254 View FIGURES 255–257 View FIGURES 258–263 View FIGURES 264–273 )

Caraphractus Walker, 1846: 49 View in CoL (key), 50 (description). Type species: Caraphractus cinctus Walker, 1846 View in CoL , by monotypy. Valkerella Westwood, 1879: 584 (footnote). Type species: Polynema natans Lubbock, 1864 View in CoL , by monotypy.

Walkerella Dalla Torre, 1898: 425 View in CoL . Unjustified emendation.

Diagnosis. Body length 795–1250 μm. Head, mesosoma, petiole and coxae heavily sculptured with isodiametric reticulations ( Figs 246–250 View FIGURE 246 View FIGURES 247–251 , 253, 254 View FIGURES 252–254 ); antenna with clava 1-segmented and widening towards apex ( Fig. 252 View FIGURES 252–254 ); fore wing with 1 distal macrochaeta, apparently without marginal vein, and with parastigmal and stigmal veins together as long as submarginal vein ( Fig. 251 View FIGURES 247–251 ).

Discussion. Among the nine other Nearctic genera of the Polynema group ( Acmopolynema , Cnecomymar , Eustochus , Kalopolynema , Mymar , Neomymar , Palaeoneura , Polynema , Stephanodes ), Caraphractus is the sister genus to Eustochus . Together they form a distinct subgroup distinguished by their heavily sculptured head, mesosoma, and petiole.

Nearctic hosts. Coleoptera : Dytiscidae .
